hammams, 1914.

To all whom 2t may concern:

Be it known `that I, SAMUEL Downs, a citizen of the United States, residing at Pitman, in the county of Gloucester and State of New Jersey, have invented certain nett7 land useful Improvements in Railway- Tie Plates, of which .the following is a speci cation.

My invention relates to improvements in railway tie plates, the object of the invention being to securely tie the rail and prevent creeping.

A further object is to provide improve ments of` this vcharacter which permit the line 2--2 of Fig. 1. Fig. 3 -is a viewfin.

section on the line 3-3 of Fig. 1, and Fig. 4 is a view in section on the line 4 4 of Fig. 1.

1 yrepresents a tie and 2 a rail extending across the' same. Between the rail 2 and the tie 1, my improved tie plate 3 is located, and is provided on itsunderface with longitudinal webs 4 which become embedded in the tie and prevent lateral movement yof the tie plate. The "plate 3 is alsoprovided with spike holes 5 for the reception of ordinary spikes 6 which-bind a inst the base flanges of the railas cleary shown. vOn the tie plate 3', at .one side ofthe rail 2, I provide a block 'I which has a serrated or toothed edge 8 located against one base flange ofthe rail. This block 7 is vsecured in place by bolts 9 which project through tie plate 1 and have nuts 10 screwed on their upper ends against the block 7. `As shown clearlyin Fig. 3, theheads 11 of these bolts are on the under face ofthe tie plate and the .tie is. recessed as shown at 12to accommodate them. The bolts have angular portions 13 which projectthroug'h angularv openings `14 -in the tie plate so as to prevent any 'rotary movement .of thebolts, allowing the '.nuts to` be Slfewed into place. On the tie plato 3, at the opposlte s1de of rail 2, I provide twol dogs 15 and. 16 which are pvotally sup `ortfed onl bolts 17 cor-responding to ..the b'o ts ,11 and-nuts 1 8 'are screwed onto the bolts above the dogs to .hold the llatter .in position. These dogs 15 and 16, at their inner wider 'ends are curved in `the are offa circle and provided with inclined weigh-19 -to engage the base ange of the ral The outer ends ofthe clogsy i12 are provided with screw-threaded pins l20 which are connected by a turn buckle 21. The

.pins 2o are :threaded in 'eppesite directions,

so that when the turn buckle is operated, the dogs 16will be moved on their pivots so as to properly adjust them to grip the base iiange ofthe rail or to release the rail whenever desired. The turn buckle 21 has openings 22 therein for the reception of a pin vto turn the same, and by means of Ithis, tuen-buckle, any desired engagement of the dogs with the rail may be had.r

It will be noted that the teeth Aof the dogs di 15'and 16 are beveled, sothat they engage oppositely. In .other words, the dog 15 prevents movement of the rail 2 in one direction, while `the'fdcg16 prevents movement of the rail inthe other direction, yet when :the rail expands o r contracts, the :particular dog eifected v.-will fonthisjmovemen f,

Various' slighty changes might be made in thegeneral form 'and arrangementof parts described without vdeparting' from my invention, and hence 1 do notlimit myself to pivot k su'iiiciently vto allow the precise details set forth, 'but .consider myselfat liberty tomake such .changesland alterations as`r fairly fall within,l the spirit and scope of the appended claims.. f Having thus described my invention, what I claim as new and desire to secure byV Letters Patent is:

1. A railwaytie plaster-ing two pivetee dogs, said dogs engaging the .same base ange of the rail, and means connecting the outer portionsof the dogs for. simultaneously operating'athe dogs to .adjust their engagement withthe rail, substantially as described.X l

...2.,A 'railway tie platehaving a toothed block secured thereto adapt-ed toengage one side of arail, two pivotedV dogs secured to the tie plate rand "having'curved toothed ends engaging the oppositev side-of the rail, andmeans for adjY 'g' thepl'es-v no f ' sure of'the'dogs `tially as described.

. 3. A railway tie plate having a toothed block secured Atheretdand adapted to engage one side of a rail, two-pivoted dogs se- 1 openings, a block having openings receiv ving two of said bolts, nuts on said last-mentioned bolts locking the block to the plate, 'said block havin a toothed .edge engaging one base flange o arail-{t'wo d pivotally supported on vother rof? said bolts, nuts on said last-mentioned bolts screwedagainst the'. dogs, said dogs at one endvcurved and against the rail, substan-l having teeth on said curved ends engaging the base aange of the mimi-imam pins connected to the dogs at theirother ends, and 'a turn buckle engagingwsaid threaded pins, substantially as described.

-5 A railway tie plate having angular openings therein, bolts having angular portionsl positioned in said angular openings, dogs pivotally lsupported between their ends on said bolts, said dogs having curved ends, and beveled teeth on the curved ends of the dogs, said d ositioned at an angle to each otheryanf .adjusting means connecting the dogs,l substantially as described.

In testimony whereof I have signed my name to this specification inthe ypresence of two subscribing witnesses.
